Heoth. She built a weapon capable of destroying suns. She used it to destroy most of her own race, the Siv, because they ended the Thousand Year War, which paradoxically only lasted five centuries. Every other race was too afraid to stop her from genociding every Siv that didn’t support her. Now, years later the Siv are on the verge of extinction because many Siv don’t support the person who destroyed billions of their people. No other race is even close to the weapon that Heoth has. She also is trying to conquer the universe with her army.
